UNITED STATES JAMES W. IVORY, OF PHILADELPHIA, '.PFl\Tl\TSLVJXLTIA..`

TOBACCO PIPE.

Application filed December 4, 1919.

To all 'LU/tom t may concern: l

Be it known that I, JAMES W. IvonY, a subject of the King ot GreatBritain, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Tobacco Pipe, of which thefollowing is a specification. I

My invention relates to an improvement in ordinary tobacco pipes wherebytobacco may be smoked dry and comfortable while avoiding clogging of thebase of the bowl and stem of the pipe, preventing Agurglng in the pipeand overcoming an excess of nicotine ljuice formingl in the base ot thebowl and stem of the pipe, and steaming otl the to,- bacco and smoke areavoided. rI`hese and other advantages are achieved by means of an innerbowl placement consisting of a vessel or tray, and an eXtra fresh airpassage, or eXtra air passages by means of a perforated stem on thebowl, `or through a perforation in the wall of the bowl at the basethereof through or around said placement, whereby said air mingles withthe smoke after the latter is created and leaves the burning tobacco, aswill be hereinafter more fully set forth.

The invention is satisfactorily illustrated in the accompanyingdrawings, but the important instrumentalities thereof may be varied, andso it is to be understood that the invention is not limited to ythespecicpdetails shown and described, as long as they are within thespirit or scope of the claims.

Figure 1 represents a longitudinal vertical section oi' a tobacco pipeembody-ing my invention.

Figure 2 represents aside elevation of a placement member detached fromFigure 1.

Figure 3 represents a vertical section of another embodiment of theinvention.

Figure 4 represents a transverse section on line 4-4 Figure 3.

Figures 5, 6, and 8 represent longitudinal sections of other embodimentsof the invention.

Figure 7 represents a bottom plan of the placement existing in Figure 6as removed therefrom.

Similar numerals oi reference indicate corresponding parts in thefigures.

Referring to the drawings,

1 designates the bowl of a tobacco pipe, and 2 designates the stemproper thereof. 3 designates a placement in the bottom por- Serial No.342,568.

tion of the Ibowl on which the tobacco is supported, .the sameconsisting of a vessel or tra-y having in the circumference thereof thechannel 4, the vertical aorts 5 leading to said channel and the threatved vertical opening 6 in which may be screwed the end ot the. stem 7,whereby said placement may be located in position and removed therefrom.as desired.

In the portion ot' the wall of the bowl opposite to the stem 2 is anenlarged oriiice 8 which receives the adjacent end of the supplementalstem 9 which extends outwardly from* said wall and has its bore 10 incommunication with the circumferentialv channel 4 of the placement.

In said placement 3 is the horizontal passage 11 which is incommunication with the ports i5 and the bore of the stem 9., it beingseen that the placement supports the tobacco `and prevents clogging oithe base of .the bowl while an eXtra volume of fresh air is drawn intothe bowl by the supplemental stem' 9 and commi-ngles with the smokeafter the latter leaves the burning tobacco in connection with the airbeing drawn through the open top of the ybowl as usual and pass ingthrough. the tobacco an eXtra volume of air then being drawn into thestem proper and from thence into the mouth thus providing a ,dry andcomfortable smoke.

Various other'iorms of accomplishing the above results are shown in theother figures as follows:

.In Figures 3 and 4 `,the supplemental stem 9 is extended through thebase portion ot the bowl under the perforated placement 3, and joins theneck 12 of the bowl. A chamber 13 exists in the base of the. bowl belowthe interior portion ot the supple mental stem 9, and a channel 14exists around said portion of the stem 9 the same being in communicationwith said chamber 13. In the wall of said supplemental stem 9 is theport 15 which forms a communica tion for the bore of the supplementalstein with said chamber 13 so that smoke is drawn in said bore andcommingles with the air entering said bore. In the base portion ot thebowl is the additional port 16 which communicates with the atmosphereand the chamber 13 and admits additional air to the latter.

In Figure 5, the supplemental stem 9 is continuous of the stem* 2 andthe bores ot said stems are also continuous. The placement has itsperforations 17 in communication with the channel 18 around thesupplemental stemi 9 whereby Smoke is directed to the chamber 19 in thebottom of the bowl, the smoke then entering the bore 10 in thesupplemental stem 9 through the port 21 in the latter.

In Figures 6 and 7 the placement consists of a block with a recess 22 inthe underside of its wall forming the flanges 21 which rest on thebottom of the bowl, the sides of said tube being cut away as at 22whereby the smoke may pass around saidsides and enter the said recess.

An auxiliary stem 23 is provided, the

, same entering the placement serving to hold the latter in position andcommunicating With the recess 22 whereby air may be admitted into thelatter' and commingle with the smo-ke in its passage to the sternproper.

In Figure 8 a portion of the auxiliary stem enters the base of the bowlthe por tion within said base being adapted to sup port the placementthereon and has the pas* sage 28 around the same to receive the smokefrom the bowl which is directed by the end of said passage as at 29 intothe bore of the neck of the bowl. Air is directed through the bore 10 ofsaid auxiliary stem to the bore in said neck and so commingled smoke andair are directed into the stem proper.

It will be seen that in Figures 3, 4, and 5, the placements aresupported on the inner end of the supplemental stems 9. In Figures 6 and7, the placement is tubular and fitted on and so supported by the innerend of the supplemental stem, said placement having therein the recess22 whereby the placement is in communication with said supplemental stemand the stem proper.

It will be seen also that whilev the placements lare supported on thesupplemental stem the tobacco `will be placed on said placements and soprevent the clogging of the bottom of the bowls.

Furthermoreas a volume of fresh air is drawn into the bowl throuffh suplementul stems and it mingles with tic smo (e drawn from the bowl thesmoking will be easy, dry, comfortable and enjoyable, obviating steamingof the smoke an tobacco in the bottom of the Ibowl and clogging in saidbottom, and the bore of the stem proper of the pipe and preventing anexcess of nicotine entering said stem nroper, and there will be nogurgling of solutions in the base of the bowl and in the stem,

The placement may be readily removed from the bowl by the handle 7,Figure 2, to the same in the opening 6, Figure 1, so as to cleanse theplacement or supply a 'fresh placement to the one that has been in use.

In some cases I provide an additional air supply by means of an extraport or aperture 16 as in Figure 3.

In some cases when it is desirable to hohl the placement in positionother than by the inner wall oi the bowl, I employ the screw 39 which ispassed upwardly through the bottom of the bowl into the placement, thehead of the screw being on the underside of said bottom where it isconvenient of access, as shown in Figure 1.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is

1. In a smoking pipe, a bowl, a stem, an auxiliary air supplying means,the latter in communication with said bowl and said stem, and aperforated lacement in the bowl in communication with said bowl and incontact with said auxiliary air supplying means.

2. In a smoking pipe, a bowl, a stem, and an auxiliary air supplyingmeans, the lat ter having on its exterior in the portion within the bowla chamber which is in coinmunicaton with said bowl and with said stem.
